ISAAC I-I. BOTTOMLEY AND THOMAS BOTTOMLEY, OF SHELF, NEAR HALIFAX,COUNTY OF YORK, ENGLAND.

DYE-VAT.

SPECIFICATION forming part of Letters Patent No. 361,921, dated April26, 1887.

Application filed June 23, 1886. Serial No. 206,051). (No model.)Patented in England September 13, 1884, No. 12,305.

To aZZ whom it may concern:

Be it known that we, Isaac HENRY Bor TOMLEY and THOMAS BOTTOMLEY,subjects of the Queen of Great Britain and Ireland, and residing atShelf, near Halifax, in the county of York, England, have inventedcertain Iniprovements in Apparatus for Boiling and Setting \VovenFabrics, (for which Letters Patent have been granted to us by theGovernment of Great Britain, No. 12,365, dated September 13, 1884,) ofwhich the following is a specification.

The object of our invention is the construction of an apparatus thatwill be applicable for the combined operations of stretching, tentering,boiling, and setting woven fabrics; and it consists in forming a deepvessel or cistern with an open top, and mounting therein adjustableguides, in the grooves of which are placed traversing chains fitted withtenteringpins, and at some distance from the said vessel or cistern wemount a shaft, upon which adjustable chain-pulleys are placed for givingmotion to the said chains. The fabric is fed onto the tentering-pinsnear the chain-pulleys, and, passing through the boiling liquor in astretched condition,is boiled and set, so that when stripped of the pinsby the strippingrollers it retains the width at which it has been set.

In the accompanying drawings, Figurelrepresents a side elevation of ourimproved apparatus. Fig. 2 is a plan of the same; Fig. 3, a sectionalelevation through line AB, and the remainder of the figures are enlargeddetails.

In all the fi gu res similar letters indicate similar parts.

The apparatus is driven by the pulleys on the revolving shaft upon whichthe pinion A is secured, the latter gearing with the teeth of wheel 13on the main shaft 0, upon which are mounted two sliding chain-pulleys, Dand D. Around each of these pulleys is an endless pitch-chain, E, havingtentering-pins F fixed to the projecting flanges F. The links of therespective pitch-chains, after leaving the pulleys D and D, pass throughthe grooved slides G and G, which extend down into the vessel or cisternand back again to the said pulleys, both guides and pulleys beingcapable of adjustment sidewise to suit the width of the fab ric to beboiled and set.

The grooved slides G and G are connected together in several places byscrews S, one portion of each screw, from the center toward the end,being cut with a left-hand thread, and the other portion with aright-hand thread, all the screws being coupled together by shafts H andwheels H and H so that by turning the handle J all the screws areactuated at the same time, thereby causing the grooved slides G and G totravel toward or from each other,

accordingvto the direction in which the said handle is turned.

In connection with the top screw, S, are two arms, K, one being ontheleft-hand portion of the screw and the other on the right-hand, bywhich the pitch-chain pulleys D and D are moved in the same directionand at the same time as the grooved slides. The slides are set a littlefarther apart at LL than where the fabric is fed onto the tentering-pinsat M M, by which arrangement the fabric is stretched and conducted atthat width through the boiling liquor, by which it is set, and finallystripped from the tenteringpins by the rollers N and and N and wrappedaround the roller N, the roller N being driven by the diagonal shaft andbevel-wheels K.

In order that the tentering-pins may take proper hold of each edge ofthe fabric as it is fed to the machine, we secure to each grooved slidea bracket, P, and joint to each a lever, one arm, It, of which is fittedwith a circular disk, T, covered with indie-rubber or felt; or a strongcircular brush may be used instead of the disk for pressing the fabriconto the said pins, the necessary pressure being obtained by theadjustable weight W on each arm It of the said levers.

The pitch-chains E are assisted through the grooved slides G and G bytwo small pitchchain pulleys, D and D", on the revolving shaft 0, drivenby the belt Z on the pulleys Z and Z. The teeth of the wheels, engagingwith the links of the said chains, assist in moving the latter throughthe grooves. The grooved slides are formed in two parts, as shown by thetransverse section, Fig. 4, the recess in the slides being largest inthe center for the reception of the links E of the pitchchains, eachlink having a projecting flange, F, which passes through the opening Q,and fitted with tentering-pins, as shown by details, Fig. 5, whichrepresents a plan, and Fig. 6, a cross-section through the chain.

WVhat We claim as onrinveution is- 1. The combination of a tank andchainguides in the tank with tentering chains adapted to traverse thesaid guides, substantially as specified.

2. The combination of a tank and laterallyadjustable chain-guides in thetank with tentering-chains traversing said guides, substantially as setforth.

3. The combination of a tank and ehainguides in the tank with pulleysand endless
